C6H8O6 i think so might be (C)

Answer:  A)  C5H8O2

Explanation:  Let's assume we have 100 grams of the unknown compound.  We can then find grams for each element by multiply it's percentage times 100g.  (e.g., carbon at 60% gives 60 grams of C).  Then divide the mass of each element by it's molar mass.  That will normalize the number of that element in relation to the others.  E,g,, the 60 grams of carbon, divided by its molar mass of 12.01 g/mole gives 5 moles of C atoms.  For H we get 8, and for O we get 2.  That gives us the empirical formula C5H8O2

How many significant digits are 6.3590x10 7 mm
Svet_ta [14]
If you go by the decimal there should be 5 significant digits because 0 is a trailing zero and matters since it comes after a decimal. however if you do 

6.3590 x 10 ^7 = 63590000 then you would only have 4 significant digits because there is no longer a decimal to make the zero after the 9, significant. 

Hope this helps!

What is the mole ratio between oxygen and carbon dioxide?<br><br> C25H52 + 38 O2 → 25 CO2 + 26 H2O
user100 [1]

Answer:

38 : 25

Explanation:

First thing's first, we have to confirm if the reaction is indeed balanced.

The equation of the reaction is given as;

C25H52 + 38 O2 → 25 CO2 + 26 H2O

From the reaction, 38 moles of O2 produces 25 moles of CO2

The ratio is given as;

38 : 25
